Most US house price models break down in the mid-2000's, due to the omission of exogenous changes in mortgage credit supply (associated with the sub-prime mortgage boom) from house price-to-rent ratio and inverted housing demand models. Previous models lack data on credit constraints facing...

The U.S. house price boom has been linked to an unsustainable easing of mortgage credit standards. However, standard time series models of US house prices omit credit constraints and perform poorly in the 2000’s. We incorporate data on credit constraints for first time buyers into a model of...

Banks operating under Value-at-Risk constraints give rise to a welldefined aggregate balance sheet capacity for the banking sector as a whole that depends on total bank capital. Equilibrium risk and market risk premiums can be solved in closed form as functions of aggregate bank capital. We...

This paper analyzes banks’ choice between lending to firms individually and sharing lending with other banks, when firms and banks are subject to moral hazard and monitoring is essential. Multiple-bank lending is optimal whenever the benefit of greater diversification in terms of higher...

Corporate finance theories suggest that problems of asymmetric information and moral hazard in credit markets can be addressed by choosing short-term maturities. Theories of debt renegotiation suggest that the credibility of the implicit commitment to not make concessions to insolvent borrowers,...

The availability of credit varies over the business cycle through shifts in the leverage of financial intermediaries. Empirically, we find that intermediary leverage is negatively aligned with the banks’ value-at-risk (VaR). Motivated by the evidence, we explore a contracting model that...

An economy is in a liquidity trap when monetary policy cannot influence either real or nominal variables of interest. A necessary condition for this is that the short nominal interest rate is constrained by its lower bound, typically zero. The paper considers two small analytical models, one...

Meltzer (2001b) argues that the current trend for downgrading the role of money in standard macro models is erroneous as it masks those monetary transmission channels which operate through changes in relative yields of assets. This paper shows that the scope of these changes can be empirically...

Governments through the ages have appropriated resources through the monopoly of the ‘coinage’. In modern fiat money economies, the monopoly of the issue of legal tender is generally assigned to an agency of the state, the Central Bank, which may have varying degrees of operational and...

We establish a set of US stylized facts on prices, quantities and balance sheets, assess the consistency of the current generation of financial DSGE models to these, and provide guidance on the challenges ahead. We mainly find four aspects which future financial friction models should take into...
